Emitters

Rating: Represents the energy load of the emitter, this can be either:

• Set manually

• Auto-filled based on the room heat load calculations

  • This is only applicable if you have used h2x for your heat load calculations

Pressure Drop: Determines the resistance in the system caused by the emitter, and will be added onto the Recirculation Pump Duty if it is the index circuit in the system.

Volume: Includes the internal water volume, which contributes to the Total System Volume.

Generic Radiators:

• These are user-defined radiators where you can manually input specifications.

• Fixed Load Rating:

  • Choose a specific heat output value for the radiator.

  • Ideal for projects where manufacturer data is unnecessary.

• Specify Dimensions and Style:

  • Input radiator Style and define dimensions like Height and Length

  • Set size limits to ensure compatibility with the design.

  • Recommended for existing radiators where the dimensions are known, allowing you to check the radiator output based on the characteristics of the new system.

Manufacturer Radiators:

• These are preloaded radiators available through the Marketplace.

• Best suited for projects that require specific manufacturer models or detailed product data.

• Range Selection:

  • Choose a specific radiator series or product line that matches your project needs.

• Height and Length Options:

  • Select predefined dimensions based on available manufacturer ranges.

  • By defining one dimension, h2x will size the other dimension

The Radiator snaps to walls automatically for alignment. 

• Hold Shift to disable snapping or Space to flip orientation.

Click once to place the Radiator. 

A second click connects it to flow and return pipes if desired.

• If you do not want to draw any pipes, click Done in the top left corner, or Esc on your keyboard

• If main pipes are not yet drawn for you to connect to, click the desired connection point, and the main pipes can be drawn and connected to them later.

Range/Style/Type: Select radiator type, model, height, length, and depth from predefined options or enter custom values.

Dimensions The radiator will automatically size the radiator’s dimensions based on water temperature, room temperature, and heat loss of the room below.

Manufacturer and Model: This is specified based on your selections, but you can update or customize it.

Rating Method: Choose between Power Rating or Flow Rate Rating:

• Power Based: This load is used to calculate the flow rate in conjunction with the system’s Delta T.

  • Note this output is auto filled based on the room and water temperature, in addition to the radiator specifications.

• Flow Based: Specify the desired flow rate, bypassing the output calculations that factor in the Delta T of the water.

Volume: Input or override the radiator's internal water volume.

Pressure Loss: Specify or override the pressure loss across the radiator.

Inlet Flow System: Set the flow system for the Radiator (e.g., Heating).

Connection Height: Adjust the Height of the inlet connection point above the floor.

Click to Place: Select the Manifold from the toolbar and click on the design workspace to position it.

Use Shortcuts: Rotate (Arrow keys) or flip inlets and outlets (Spacebar) as needed.

Connection Options:

• Snap to nearby walls for automatic alignment.

• Hold Shift to avoid snapping to walls.

• Manually connect pipes to supply and return inlets.

Width and Depth: Adjust dimensions for accurate representation.

Color: Customize the manifold's appearance for easy identification.

Connected Rooms: Select associated Rooms from the drop-down list.

• If heat load calculations are performed in h2x, the manifold will automatically size to meet the connected rooms' demands.

Underfloor Mode: Toggle to enable Underfloor Heating functionality between full loop design or approximate which will provide hatching to the room.

Underfloor Flow System: Choose the flow system used for underfloor heating.

Rating Method: Choose between Load-Based Rating or Flow-Based Rating:

• Load-Based: Enter the required heat load. This will autofill based no Connected Rooms.

• Flow-Based: Enter the desired flow rate directly.

Volume: Input or override the manifold's internal water volume.

Pressure Loss: Specify or override the pressure loss across the manifold.

Has Recirculation Pump: Toggle this option if the manifold includes a Recirculation Pump.

Manufacturers:

• Manifold Manufacturer: Select the manifold's manufacturer from the drop-down list.

• Ball Valve Manufacturer: Specify the manufacturer of the ball valves used.

• Actuator Manufacturer: Select the actuator manufacturer for compatibility.

• Pump Pack Manufacturer: Input the pump pack manufacturer for system documentation.

UFH Flow Temperature: Review or override the Flow Temperature for underfloor heating.

UFH Return Temperature: Review or override the Return Temperature for underfloor heating.

Inlet Flow System: Set the flow system for the Manifold (e.g., Heating).

Connection Height: Adjust the Height of the inlet connection point above the floor.

Click to Place: Select the FCU from the toolbar and click on the design workspace to position it.

Use Shortcuts: Rotate (Arrow keys) or flip inlets and outlets (Spacebar) as needed.

Connect Pipes: Draw Pipes to connect the FCU to the system.

• Flow Connection: Ensure the flow pipe connects to the top inlet of the FCU.

• Return Connection: Connect the return pipe to the bottom outlet, which is indicated by the presence of a balancing valve.

Shape: Select between rectangular or cylindrical shapes based on the design requirements.

Width and Depth: Specify the unit's dimensions.

Color: Customize the appearance for easy identification.

Inlet/Outlet Activation: Option to Enable or Disable the heating or chilled water connection points.

Flow System: Specify the System type (e.g., heating, chilled) the FCU connects to.

Associated Rooms: Choose between two options:

• Auto-fill the heating/chilled load based on associated room heat load calculations performed in h2x.

• Manually input the load rating for custom requirements.

Volume: Input or override the internal water capacity of the FCU for the heating/chilled system.

Pressure Loss: Input or override the pressure loss of the FCU for the heating/chilled system.

Connection Height: Adjust the height of the connection point above the floor to match the building layout or pipe elevations.

Click to Place: Select the AHU from the toolbar and click on the design workspace to position it.

Use Shortcuts: Rotate (Arrow keys) or flip inlets and outlets (Spacebar) as needed.
